Clinical chorioamnionitis at term: definition, pathogenesis, microbiology, diagnosis, and treatment. Am J Obstet Gynecol 2024; 230:S807-S840. [PMID: 38233317 PMCID: PMC11288098 DOI: 10.1016/j.ajog.2023.02.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 01/31/2023] [Accepted: 02/02/2023] [Indexed: 04/05/2023]
Abstract
Clinical chorioamnionitis, the most common infection-related diagnosis in labor and delivery units, is an antecedent of puerperal infection and neonatal sepsis. The condition is suspected when intrapartum fever is associated with two other maternal and fetal signs of local or systemic inflammation (eg, maternal tachycardia, uterine tenderness, maternal leukocytosis, malodorous vaginal discharge or amniotic fluid, and fetal tachycardia). Clinical chorioamnionitis is a syndrome caused by intraamniotic infection, sterile intraamniotic inflammation (inflammation without bacteria), or systemic maternal inflammation induced by epidural analgesia. In cases of uncertainty, a definitive diagnosis can be made by analyzing amniotic fluid with methods to detect bacteria (Gram stain, culture, or microbial nucleic acid) and inflammation (white blood cell count, glucose concentration, interleukin-6, interleukin-8, matrix metalloproteinase-8). The most common microorganisms are Ureaplasma species, and polymicrobial infections occur in 70% of cases. The fetal attack rate is low, and the rate of positive neonatal blood cultures ranges between 0.2% and 4%. Intrapartum antibiotic administration is the standard treatment to reduce neonatal sepsis. Treatment with ampicillin and gentamicin have been recommended by professional societies, although other antibiotic regimens, eg, cephalosporins, have been used. Given the importance of Ureaplasma species as a cause of intraamniotic infection, consideration needs to be given to the administration of antimicrobial agents effective against these microorganisms such as azithromycin or clarithromycin. We have used the combination of ceftriaxone, clarithromycin, and metronidazole, which has been shown to eradicate intraamniotic infection with microbiologic studies. Routine testing of neonates born to affected mothers for genital mycoplasmas could improve the detection of neonatal sepsis. Clinical chorioamnionitis is associated with decreased uterine activity, failure to progress in labor, and postpartum hemorrhage; however, clinical chorioamnionitis by itself is not an indication for cesarean delivery. Oxytocin is often administered for labor augmentation, and it is prudent to have uterotonic agents at hand to manage postpartum hemorrhage. Infants born to mothers with clinical chorioamnionitis near term are at risk for early-onset neonatal sepsis and for long-term disability such as cerebral palsy. A frontier is the noninvasive assessment of amniotic fluid to diagnose intraamniotic inflammation with a transcervical amniotic fluid collector and a rapid bedside test for IL-8 for patients with ruptured membranes. This approach promises to improve diagnostic accuracy and to provide a basis for antimicrobial administration.

Abstract
Importance Intra-amniotic infection (IAI) is a common condition with potentially devastating maternal and neonatal complications. However, there are incomplete data regarding the most effective antimicrobial treatment regimen for this condition. Objective This article aims to review the current evidence and recommendations for intrapartum and postpartum management of IAI. Evidence Acquisition Original research articles, review articles, and guidelines on IAI were reviewed. Results Numerous known risk factors for IAI exist, some of which are modifiable. Serious neonatal complications can result from exposure to IAI including increased risk of preterm birth and neonatal death. Possible maternal complications include increased risk of cesarean delivery, postpartum hemorrhage, and postpartum endometritis. Antibiotics are the mainstay of treatment for IAI for both mothers and neonates, although there is no consensus on which antimicrobial agents are best and the appropriate duration of therapy. Conclusions and Relevance Monitoring patients for signs of IAI, proper treatment, and communication of the diagnosis with the pediatric team are essential for preventing maternal and neonatal complications of IAI. More research is needed to determine the proper treatment regimens for both mothers diagnosed with IAI and their neonates.

Abstract
INTRODUCTION Transrectal prostate biopsies are associated with post biopsy infection and sepsis. We compared the efficacy of povidone-iodine rectal disinfection versus formalin needle disinfection in preventing post biopsy infection among patients undergoing transrectal ultrasound-guided prostate biopsy. METHODS Patients scheduled to undergo ultrasound-guided transrectal prostate biopsy (n = 621) over 20 months were randomized into 2 groups to receive either povidone-iodine intrarectal disinfection or formalin disinfection of needle after each core. These were compared to assess which methodology better prevented postprocedure infection. Statistical analysis were used to identify independent factors promoting infections. RESULTS Two hundred and ninety-eight patients from povidone-iodine intrarectal disinfection were compared with 300 from formalin needle disinfection group. Formalin needle disinfection was associated with significantly more infections (P = 0.02). Escherichia coli was the dominant pathogen, with >50% of cases being quinolone resistant. Type of disinfection (P = 0.002), BMI (P = 0.001), chronic prostatitis (P = 0.002), and diabetes mellitus (P = 0.01) were independent predictors of infections. BMI at 28.95 kg/m2 provided the best predictive cut-off point for infections, irrespective of method of disinfection. Area under the curve for all these parameters together was 0.91. CONCLUSIONS We conclude that along with oral cephalosporin prophylaxis, povidone-iodine intrarectal disinfection is a superior to formalin needle disinfection alone in preventing post biopsy infection. Patients with BMI >28.95 kg/m2 should be considered at a higher risk for infections.

Int Wound J 2021; 19:211-221.

Abstract
We aimed to create and validate a natural language processing algorithm to extract wound infection-related information from nursing notes. We also estimated wound infection prevalence in homecare settings and described related patient characteristics. In this retrospective cohort study, a natural language processing algorithm was developed and validated against a gold standard testing set. Cases with wound infection were identified using the algorithm and linked to Outcome and Assessment Information Set data to identify related patient characteristics. The final version of the natural language processing vocabulary contained 3914 terms and expressions related to the presence of wound infection. The natural language processing algorithm achieved overall good performance (F-measure = 0.88). The presence of wound infection was documented for 1.03% (n = 602) of patients without wounds, for 5.95% (n = 3232) of patients with wounds, and 19.19% (n = 152) of patients with wound-related hospitalisation or emergency department visits. Diabetes, peripheral vascular disease, and skin ulcer were significantly associated with wound infection among homecare patients. Our findings suggest that nurses frequently document wound infection-related information. The use of natural language processing demonstrated that valuable information can be extracted from nursing notes which can be used to improve our understanding of the care needs of people receiving homecare. By linking findings from clinical nursing notes with additional structured data, we can analyse related patients' characteristics and use them to develop a tailored intervention that may potentially lead to reduced wound infection-related hospitalizations.

Abstract
OBJECTIVES Clinical chorioamnionitis at term is considered the most common infection-related diagnosis in labor and delivery units worldwide. The syndrome affects 5-12% of all term pregnancies and is a leading cause of maternal morbidity and mortality as well as neonatal death and sepsis. The objectives of this study were to determine the (1) amniotic fluid microbiology using cultivation and molecular microbiologic techniques; (2) diagnostic accuracy of the clinical criteria used to identify patients with intra-amniotic infection; (3) relationship between acute inflammatory lesions of the placenta (maternal and fetal inflammatory responses) and amniotic fluid microbiology and inflammatory markers; and (4) frequency of neonatal bacteremia. METHODS This retrospective cross-sectional study included 43 women with the diagnosis of clinical chorioamnionitis at term. The presence of microorganisms in the amniotic cavity was determined through the analysis of amniotic fluid samples by cultivation for aerobes, anaerobes, and genital mycoplasmas. A broad-range polymerase chain reaction coupled with electrospray ionization mass spectrometry was also used to detect bacteria, select viruses, and fungi. Intra-amniotic inflammation was defined as an elevated amniotic fluid interleukin-6 (IL-6) concentration ≥2.6 ng/mL. RESULTS (1) Intra-amniotic infection (defined as the combination of microorganisms detected in amniotic fluid and an elevated IL-6 concentration) was present in 63% (27/43) of cases; (2) the most common microorganisms found in the amniotic fluid samples were Ureaplasma species, followed by Gardnerella vaginalis; (3) sterile intra-amniotic inflammation (elevated IL-6 in amniotic fluid but without detectable microorganisms) was present in 5% (2/43) of cases; (4) 26% of patients with the diagnosis of clinical chorioamnionitis had no evidence of intra-amniotic infection or intra-amniotic inflammation; (5) intra-amniotic infection was more common when the membranes were ruptured than when they were intact (78% [21/27] vs. 38% [6/16]; p=0.01); (6) the traditional criteria for the diagnosis of clinical chorioamnionitis had poor diagnostic performance in identifying proven intra-amniotic infection (overall accuracy, 40-58%); (7) neonatal bacteremia was diagnosed in 4.9% (2/41) of cases; and (8) a fetal inflammatory response defined as the presence of severe acute funisitis was observed in 33% (9/27) of cases. CONCLUSIONS Clinical chorioamnionitis at term, a syndrome that can result from intra-amniotic infection, was diagnosed in approximately 63% of cases and sterile intra-amniotic inflammation in 5% of cases. However, a substantial number of patients had no evidence of intra-amniotic infection or intra-amniotic inflammation. Evidence of the fetal inflammatory response syndrome was frequently present, but microorganisms were detected in only 4.9% of cases based on cultures of aerobic and anaerobic bacteria in neonatal blood.

Conde-Agudelo A, Romero R, Jung EJ, Garcia Sánchez ÁJ. Management of clinical chorioamnionitis: an evidence-based approach. Am J Obstet Gynecol 2020; 223:848-869. [PMID: 33007269 PMCID: PMC8315154 DOI: 10.1016/j.ajog.2020.09.044] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 09/08/2020] [Accepted: 09/24/2020] [Indexed: 02/09/2023]
Abstract
This review aimed to examine the existing evidence about interventions proposed for the treatment of clinical chorioamnionitis, with the goal of developing an evidence-based contemporary approach for the management of this condition. Most trials that assessed the use of antibiotics in clinical chorioamnionitis included patients with a gestational age of ≥34 weeks and in labor. The first-line antimicrobial regimen for the treatment of clinical chorioamnionitis is ampicillin combined with gentamicin, which should be initiated during the intrapartum period. In the event of a cesarean delivery, patients should receive clindamycin at the time of umbilical cord clamping. The administration of additional antibiotic therapy does not appear to be necessary after vaginal or cesarean delivery. However, if postdelivery antibiotics are prescribed, there is support for the administration of an additional dose. Patients can receive antipyretic agents, mainly acetaminophen, even though there is no clear evidence of their benefits. Current evidence suggests that the administration of antenatal corticosteroids for fetal lung maturation and of magnesium sulfate for fetal neuroprotection to patients with clinical chorioamnionitis between 24 0/7 and 33 6/7 weeks of gestation, and possibly between 23 0/7 and 23 6/7 weeks of gestation, has an overall beneficial effect on the infant. However, delivery should not be delayed to complete the full course of corticosteroids and magnesium sulfate. Once the diagnosis of clinical chorioamnionitis has been established, delivery should be considered, regardless of the gestational age. Vaginal delivery is the safer option and cesarean delivery should be reserved for standard obstetrical indications. The time interval between the diagnosis of clinical chorioamnionitis and delivery is not related to most adverse maternal and neonatal outcomes. Patients may require a higher dose of oxytocin to achieve adequate uterine activity or greater uterine activity to effect a given change in cervical dilation. The benefit of using continuous electronic fetal heart rate monitoring in these patients is unclear. We identified the following promising interventions for the management of clinical chorioamnionitis: (1) an antibiotic regimen including ceftriaxone, clarithromycin, and metronidazole that provides coverage against the most commonly identified microorganisms in patients with clinical chorioamnionitis; (2) vaginal cleansing with antiseptic solutions before cesarean delivery with the aim of decreasing the risk of endometritis and, possibly, postoperative wound infection; and (3) antenatal administration of N-acetylcysteine, an antioxidant and antiinflammatory agent, to reduce neonatal morbidity and mortality. Well-powered randomized controlled trials are needed to assess these interventions in patients with clinical chorioamnionitis.

Abstract
Objective To assess the impact of gestational weight gain >20 pounds (more than Institute of Medicine [IOM] recommendations) on postpartum infectious morbidity in women with class III obesity. Methods This is a retrospective cohort of term, nonanomalous singleton pregnancies with body mass index ≥40 at a single institution from 2013 to 2017. Pregnancies with multiple gestation, late entry to care, and missing weight gain data are excluded. Primary outcome is a composite of postpartum infection (endometritis, urinary tract, respiratory, and wound infection). Secondary outcomes include components of composite, wound complication, readmission, and blood transfusion. Bivariate statistics compared demographics, pregnancy complications, and delivery characteristics of women exceeding IOM guidelines (GT20) with those who did not (LT20). Regression models were used to estimate adjusted odds of outcomes. Results Of 374 women, 144 (39%) gained GT20 and 230 (62%) gained LT20. Primiparous, nonsmokers more likely gained GT20 ( p < 0.05). No significant difference in other demographics. Among women who gained GT20, 10.4% had postpartum infectious morbidity compared with 3.0% in LT20 ( p < 0.01). Wound infection is more common in the GT20 group (7.6 vs. 2%, p = 0.02). After adjustment, women who gained GT20 had threefold higher odds of postpartum infectious morbidity (adjusted odds ratio: 3.17, 95% confidence interval: 1.17, 8.60). Conclusion Women with class III obesity who gain more than the IOM recommends are at increased risk for postpartum infectious morbidity.

Abstract
Background The aim of our study was to analyze the risk factors of nosocomial infection after cardiac surgery in children with congenital heart disease (CHD). Methods We performed a retrospective cohort study, and children with CHD who underwent open-heart surgeries at Shanghai Children’s Medical Center from January 1, 2012 to December 31, 2018 were included. The baseline characteristics of these patients of different ages, including neonates (0–1 months old), infants (1–12 months old) and children (1–10 years old), were analyzed, and the association of risk factors with postoperative nosocomial infection were assessed. Results A total of 11,651 subjects were included in the study. The overall nosocomial infection rate was 10.8%. Nosocomial infection rates in neonates, infants, and children with congenital heart disease were 32.9, 15.4, and 5.2%, respectively. Multivariate logistic regression analysis found age (OR 0798, 95%CI: 0.769–0.829; P < 0.001), STS risk grade (OR 1.267, 95%CI: 1.159–1.385; P < 0.001), body mass index (BMI) <5th percentile (OR 1.295, 95%CI: 1.023–1.639; P = 0.032), BMI >95th percentile (OR 0.792, 95%CI: 0.647–0.969; P = 0.023), cardiopulmonary bypass (CPB) time (OR 1.008, 95%CI: 1.003–1.012; P < 0.001) and aortic clamping time (OR 1.009, 1.002–1.015; P = 0.008) were significantly associated with nosocomial infection in CHD infants. After adjusted for confounding factors, we found STS risk grade (OR 1.38, 95%CI: 1.167–1.633; P < 0.001), BMI < 5th percentile (OR 1.934, 95%CI: 1.377–2.715; P < 0.001), CPB time (OR 1.018, 95%CI: 1.015–1.022; P < 0.001), lymphocyte/WBC ratio<cut off value (OR 3.818, 95%CI: 1.529–9.533; P = 0.004) and AST>cut off value (OR 1.546, 95%CI: 1.119–2.136; P = 0.008) were significantly associated with nosocomial infection in CHD children. Conclusion Our study suggested STS risk grade, BMI, CPB duration, low lymphocyte/WBC or high neutrophil/WBC ratio were independently associated with nosocomial infection in CHD infant and children after cardiac surgery.

Preoperative cefazolin rather than clindamycin or metronidazole is associated with lower postpartum infection among women with chorioamnionitis delivering by cesarean delivery. Am J Obstet Gynecol MFM 2019; 2:100074. [PMID: 33345988 DOI: 10.1016/j.ajogmf.2019.100074] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2019] [Revised: 11/13/2019] [Accepted: 11/17/2019] [Indexed: 11/21/2022]
Abstract
BACKGROUND The optimal antibiotic regimen to prevent maternal postpartum infection among high-risk women treated for chorioamnionitis delivering by cesarean delivery remains to be defined. Emerging data suggest that cefazolin decreases the risk of cesarean surgical site infection. OBJECTIVE To investigate whether intrapartum antibiotic therapy with cefazolin versus the current standard clindamycin or metronidazole decreases the risk of postpartum infectious morbidity among women delivering by cesarean delivery who were receiving a base regimen of ampicillin or penicillin with gentamicin for chorioamnionitis. MATERIALS AND METHODS A secondary analysis from the Maternal-Fetal Medicine Units Network (MFMU) Cesarean Registry. We included women who delivered by cesarean delivery with presumptive chorioamnionitis (intrapartum fever >100.4°F and receipt of intrapartum antibiotics). All women received a base regimen of penicillin or ampicillin with gentamicin. We compared antibiotic therapy with cefazolin versus clindamycin or metronidazole. The primary outcome was a composite of postpartum maternal infection, including endometritis and surgical site infection. Multivariable logistic regression was used, adjusting for age, parity, race/ethnicity, insurance, body mass index at delivery, tobacco use, pregestational diabetes, American Society of Anesthesiologists classification, trial of labor prior to cesarean delivery, and postpartum antibiotics. RESULTS Among 1105 women with presumptive chorioamnionitis who delivered by cesarean delivery, 22.0% (n = 244) received cefazolin and 77.9% (n = 861) received clindamycin or metronidazole. Most women were in labor prior to cesarean delivery (93.8%) and received postpartum antibiotics (88.4%). Almost one-tenth (9.5%) were diagnosed with a postpartum infection, most commonly endometritis (80.9%), followed by surgical site infection (20.9%) (not mutually exclusive). Women treated with cefazolin rather than clindamycin or metronidazole had lower odds of postpartum infectious morbidity (adjusted odds ratio, 0.49; 95% confidence interval, 0.26-0.90). This association held when the outcome was restricted to surgical site infection (adjusted odds ratio, 0.11; 95% confidence interval, 0.01-0.92) but not endometritis. Similar results were observed with propensity score analysis. CONCLUSION Among women delivering by cesarean delivery who were treated for chorioamnionitis, additional antibiotic therapy with cefazolin decreased the risk of postpartum infection, primarily surgical site infection, compared to the current standard clindamycin or metronidazole.

Abstract
Despite persistent concerns about high cesarean delivery rates internationally, there has been less attention on improving perioperative outcomes for the millions of women who will experience a cesarean delivery each year. Enhanced recovery after surgery, a standardized, evidence-based, interdisciplinary protocol, has been successfully used in other surgical specialties including gynecology to improve quality of care and patient satisfaction while reducing overall health care costs through reduced length of stay. Enhanced recovery after surgery society guidelines for cesarean delivery were just released in August 2018. Obstetric patients, who face the dual challenge of being postpartum and postoperative, could benefit greatly from protocols that optimize their return to physiological function and reduce surgical morbidity. Although enhanced recovery after surgery has been widespread in other surgical specialties, uptake of this protocol in obstetrics has lagged behind. We believe enhanced recovery after surgery for cesarean delivery can effectively address 3 challenges faced by obstetrician/gynecologists. These are: (1) improving care for the high number of women undergoing cesarean deliveries; (2) using evidence-based care bundles to prevent maternal morbidity and mortality, address disparities, and reduce costs; and (3) limiting postoperative opioid prescribing in response to the opioid crisis. Enhanced recovery after surgery for cesarean delivery and other standardized care protocols have the potential to reduce the disproportionately high rates of maternal morbidity and mortality in the United States, and ensure all patients, regardless of demographics or location, receive the same level of high-quality peripartum care.

Abstract
BACKGROUND The incidence of post cesarean intra-abdominal infection (IAI) and the independent risk factors associated with it were retrospectively studied at a tertiary referral hospital in Egypt. METHODS The study targeted the period between January 2014 and December 2017 (4 years) at Minia University Hospital for Obstetrics and Gynecology (a tertiary referral hospital), Minia Governorate, Egypt. All cases that developed IAI following cesarean section (CS) during the study period were included (408 cases, which served as the case group); in addition, 1300 cases that underwent CS during the study period and were not complicated by IAI or surgical site Infection (SSI) were randomly chosen from the records (control group). The records of cases and controls were compared and bivariate analysis and multivariate logistic regression were used to identify risk factors for IAI. RESULTS During the studied period, there were 35,500 deliveries in the hospital, and 14200 cases (40%) of these were by cesarean section, producing a rate of 40%. The incidence of IAI post CS was 2.87%, and the mortality rate was 1.2% (due to septicemia). The most identifiable risk factors for IAI were chorioamnionitis (AOR 9.54; 95% CI =6.15-16.2; p ≤ 0.001) and premature rupture of membranes (PROM) (AOR 7.54; 95% CI =5.69-10.24; p ≤ 0.001). Risk factors also included: prolonged duration of CS > 1 h (AOR 3.42; 95% CI =2.45-5.23; p = 0.005), no antenatal care (ANC) visits (AOR 3.14; 95% CI =2.14-4.26; p = 0.003), blood loss > 1000 ml (AOR 2.86; 95% CI =2.04-3.92; p = 0.011), emergency CS (AOR 2.24; 95% CI =1.78-3.29; p = 0.016), prolonged labor ≥24 h. (AOR 1.76; 95% CI =1.26-2.27; p = 0.034) and diabetes mellitus (AOR 1.68; 95% CI =1.11-2.39; p = 0.021). CONCLUSIONS The incidence of IAI post CS in our hospital was 2.87%. Identification of predictors and risk factors for IAI is an important preventive measure.

Abstract
Background: Chorioamnionitis affects 1-4% of pregnancies, and patients who undergo cesarean delivery in the setting of chorioamnionitis have an increased risk of endometritis and surgical site infection (SSI). The standard treatment for chorioamnionitis after cesarean delivery is a combination regimen of intravenous ampicillin, gentamicin, and clindamycin with variable duration (single dose to 24 h). However, newer evidence suggests that ertapenem may decrease the risk of postoperative infectious morbidity with the added benefit of a single postpartum dose, compared to between 3 and 10 doses of AGC. Concerns regarding the cost of ertapenem have been cited as a deterrent for this regimen.Objective: The objective of this study was to investigate the cost-effectiveness of single-dose ertapenem compared to existing standard regimens.Methods: A decision analytic cost-effectiveness model was designed from a hospital perspective to compare four strategies for the postpartum management of chorioamnionitis after cesarean delivery: (i) no antibiotics; (ii) a one-time intravenous dose of ampicillin, gentamicin, and clindamycin (AGC-1); (iii) 24-h coverage with intravenous ampicillin, gentamicin, and clindamycin (AGC-24); and (iv) intravenous ertapenem, one dose. Medical costs, rates of SSI and endometritis following cesarean delivery, and costs of postcesarean infection (SSI or endometritis) were abstracted from the literature. Antibiotic drug costs were obtained from the pharmacy department at a private academic hospital. The cost of each regimen was calculated as costs to the hospital and included antibiotics (no antibiotics $0, AGC-1 $66, ertapenem $140, and AGC-24 $208), administration, and labor costs. Effectiveness was quantified as percentage of patients who avoided postcesarean infectious morbidity (endometritis or SSI).Results: The base case cost of each strategy was: AGC-1 $704, ertapenem $733, AGC-24 $846, and no antibiotics $971. Ertapenem had an effectiveness of 88%, AGC-1 and AGC-24 were 87% each, and no antibiotics was 81%. No antibiotics and AGC-24 were more costly and equally or less effective than comparators (dominated strategies). Ertapenem was more costly, but more effective than AGC-1, with an incremental cost-effectiveness ratio of $3738 per infection avoided. In a sensitivity analysis comparing ertapenem to the most commonly used strategy of ACG-24, the ertapenem strategy remained less costly if the rate of endometritis with ertapenem was <11% (base case estimate 8%) or the rate of SSI with ertapenem was <7% (base case estimate 4%).Conclusions: Ertapenem is a cost-saving alternative to 24-h AGC treatment for chorioamnionitis in the setting of cesarean delivery, and may be considered a cost-effective treatment when compared to a one time dose of AGC depending on infection rates.

Abstract
OBJECTIVE To determine the diagnosis criteria and management of intra-uterine inflammation or infection (Triple I, III). METHODS PubMed and Cochrane Central databases search. RESULTS III is defined as an infection of the fetal membranes, and/or other components like the decidua, fetus, amniotic fluid or placenta. This word should be preferred to the word chorioamnionitis that is less precise (Professional consensus). III clinical signs exhibit poor limited sensibility and specificity (EL3). The diagnosis of III is retained in case of maternal fever (defined by a body temperature≥38°C) with no alternative cause identified and at least 2 signs among the following: fetal tachycardia>160 bpm for 10min or longer, uterine pain of labor, purulent fluid from the cervical canal (Professional consensus). Maternal hyperleukocytosis>20 giga/L in the absence of corticosteroids treatment or increased plasmatic C-reactive protein also argue for III, despite their limited sensibility and specificity (EL3). III requires prompt delivery (Grade A). III is not by itself an indication for cesarean delivery (Professional consensus). Antibiotic treatment should cover Streptococcus agalactiae and Escherichia coli. Antibiotics should be started immediately and maintained all over delivery, to reduce neonatal and maternal morbidity (Grade B). Treatment should rely on a combination of betalactamin and aminoglycoside (Grade B). After vaginal delivery, one single dose of antibiotic is required. Antibiotic duration should be longer in case of bacteremia. Longer duration could be considered in case of persistent fever or of cesarean delivery (Professional consensus).

Abstract
Objective To explore risk factors of infectious complications following transrectal ultrasound-guided prostate biopsy (TRUSPB). Methods We retrospectively analyzed 1,203 patients with suspected prostate cancer who underwent TRUSPB at our center between December 2012 and December 2016. Demographics, clinical characteristics, and data regarding complications were collected, and then univariate and multivariate logistic regression analyses were used to identify independent risk factors for infectious complications after prostate biopsy. Results Multivariate logistic analysis demonstrated that body mass index (BMI) (OR=2.339, 95% CI 2.029–2.697, P<0.001), history of diabetes (OR=2.203, 95% CI 1.090–4.455, P=0.028), and preoperative catheterization (OR=2.303, 95% CI 1.119–4.737, P=0.023) were risk factors for infection after prostate biopsy. The area under the receiver operating characteristics curve for infectious complications was 0.930 (95% CI 0.907–0.953, P<0.001). BMI=28.196 kg/m2 was the best cut-off threshold for predicting infection after TRUSPB. Conclusion BMI >28.196 kg/m2, history of diabetes, and preoperative catheterization are independent risk factors for infection after prostate biopsy.

Abstract
OBJECTIVE To determine the association between maternal obesity and delivery due to chorioamnionitis prior to labor onset, among expectantly managed women with preterm premature rupture of membranes (pPROM). METHODS This was a secondary analysis of a multicenter randomized trial of magnesium sulfate versus placebo to prevent cerebral palsy or death among offspring of women with anticipated delivery at 24-31-week gestation. After univariable analysis, Cox proportional hazard evaluated the association between maternal obesity and chorioamnionitis, while Laplace regression investigated how obesity affects the gestational age at delivery of the first 20% of women developing the outcome of interest. RESULTS A total of 164 of the 1942 women with pPROM developed chorioamnionitis prior to labor onset. Obese women had a 60% increased hazard of developing such complication (adjusted HR 1.6, 95%CI 1.1-2.1, p = .008), prompting delivery 1.5 weeks earlier, as the 20th survival percentile was 27.2-week gestation (95%CI 26-28.6) among obese as opposed to 28.8 weeks (95%CI 27.4-30.1) (p = .002) among nonobese women. CONCLUSIONS Maternal obesity is a risk factor for chorioamnionitis prior to labor onset. Future studies will determine if obesity is important enough to change the management of latency after pPROM according to maternal BMI.

Abstract
PURPOSE To identify the rate of surgical site infection (SSI) after Cesarean delivery (CD) and determine risk factors predictive for infection at a large academic institution. METHODS This was a retrospective cohort study in women undergoing CD during 2013. SSIs were defined by Centers for Disease Control (CDC) criteria. Chi square and t-tests were used for bivariate analysis and multivariate logistic regression was used to identify SSI risk factors. RESULTS In 2419 patients, the rate of SSI was 5.5% (n = 133) with cellulitis in 4.9% (n = 118), deep incisional infection in 0.6% (n = 15) and intra-abdominal infection in 0.3% (n = 7). On multivariate analysis, SSI was higher among CD for labor arrest (OR 2.4; 95%CI 1.6-3.5; p <.001). Preterm labor (OR 2.8; 95%CI 1.3-6.0; p = .01) and general anesthesia (OR 4.4; 95%CI 2.0-9.8; p = .003) were predictive for SSI. Increasing BMI (OR 1.1; 95%CI 1.05-1.09; p = .02), asthma (OR 1.9; 95%CI 1.1-3.2; p = .02) and smoking (OR 1.9; 95%CI 1.1-3.2; p = .02) were associated with increased SSI. CONCLUSIONS Several patient and surgical variables are associated with increased rate of SSI after CD. Identification of risk factors for SSI after CD is important for targeted implementation of quality improvement measures and infection control interventions.

Twenty-four percent of patients with clinical chorioamnionitis in preterm gestations have no evidence of either culture-proven intraamniotic infection or intraamniotic inflammation. Am J Obstet Gynecol 2017; 216:604.e1-604.e11. [PMID: 28257964 PMCID: PMC5769703 DOI: 10.1016/j.ajog.2017.02.035] [Citation(s) in RCA: 72] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2016] [Revised: 02/15/2017] [Accepted: 02/21/2017] [Indexed: 12/23/2022]
Abstract
BACKGROUND Recent studies on clinical chorioamnionitis at term suggest that some patients with this diagnosis have neither intraamniotic infection nor intraamniotic inflammation. A false-positive diagnosis of clinical chorioamnionitis in preterm gestation may lead to unwarranted preterm delivery. OBJECTIVE We sought to determine the frequency of intraamniotic inflammation and microbiologically proven amniotic fluid infection in patients with preterm clinical chorioamnionitis. STUDY DESIGN Amniocentesis was performed in singleton pregnant women with preterm clinical chorioamnionitis (<36 weeks of gestation). Amniotic fluid was cultured for aerobic and anaerobic bacteria and genital mycoplasmas and assayed for matrix metalloproteinase-8 concentration. Microbial invasion of the amniotic cavity was defined as a positive amniotic fluid culture; intraamniotic inflammation was defined as an elevated amniotic fluid matrix metalloproteinase-8 concentration of >23 ng/mL. Nonparametric and survival techniques were used for analysis. RESULTS Among patients with preterm clinical chorioamnionitis, 24% (12/50) had neither microbiologic evidence of intraamniotic infection nor intraamniotic inflammation. Microbial invasion of the amniotic cavity was present in 34% (18/53) and intraamniotic inflammation in 76% (38/50) of patients. The most common microorganisms isolated from the amniotic cavity were the Ureaplasma species. Finally, patients without microbial invasion of the amniotic cavity or intraamniotic inflammation had significantly lower rates of adverse outcomes (including lower gestational age at delivery, a shorter amniocentesis-to-delivery interval, acute histologic chorioamnionitis, acute funisitis, and significant neonatal morbidity) than those with microbial invasion of the amniotic cavity and/or intraamniotic inflammation. CONCLUSION Among patients with preterm clinical chorioamnionitis, 24% had no evidence of either intraamniotic infection or intraamniotic inflammation, and 66% had negative amniotic fluid cultures, using standard microbiologic techniques. These observations call for a reexamination of the criteria used to diagnose preterm clinical chorioamnionitis.

Association of Body Mass Index With Infectious Complications in Free Tissue Transfer for Head and Neck Reconstructive Surgery. JAMA Otolaryngol Head Neck Surg 2017; 143:574-579.

Abstract
Importance Elevated body mass index (BMI) has been proposed as a risk factor for morbidity and mortality among patients undergoing surgery. Conversely, an elevated BMI may confer a protective effect on perioperative morbidity. Objective To examine whether an elevated BMI is an independent risk factor for perioperative and postoperative infectious complications after free tissue transfer in head and neck reconstructive surgery. Design, Setting, and Participants This cohort study included patients undergoing major head and neck surgery requiring free tissue transfer at a tertiary care center. Data were collected for 415 patients treated from January 1, 2007, through December 31, 2014. Main Outcomes and Measures The outcome of interest was postoperative infection and complications after head and neck surgery using free flaps. Covariates considered for adjustment in the statistical model included alcohol consumption (defined as >5 drinks per day [eg, 360 mL of beer, 150 mL of wine, or 45 mL of 80-proof spirits]), type 2 diabetes, prior radiotherapy, anesthesia time, hypothyroidism, smoking, American Society of Anesthesiologists classification, antibiotic regimen received (defined as a standard regimen of a first- or second-generation cephalosporin with or without metronidazole hydrochloride vs an alternative antibiotic regimen for patients allergic to penicillin), and primary surgeon. A multiple logistic regression model was developed for the incidence of the infection end point as a function of elevated BMI (>30.0). Results Among the 415 patients included in this study (277 men [66.7%] and 138 women [33.2%]; mean [SD] age, 61.5 [13.9] years), type 2 diabetes and use of an alternative antibiotic regimen were found to be independently associated with increased infectious complications after free flap surgery of the head and neck, with estimated odds ratios of 2.78 (95% CI, 1.27-6.09) and 2.67 (95% CI, 1.14-6.25), respectively, in the multiple logistic regression model. However, a high BMI was not found to be statistically significant as an independent risk factor for postoperative infectious complication (estimated odds ratio, 1.19; 95% CI, 0.48-2.92). Conclusions and Relevance Elevated BMI does not seem to play a role as an independent risk factor in postoperative complications in free tissue transfer in head and neck surgery.
